65Si2Ti钢筋是由上海市建筑科学研究所、新沪钢铁厂和上海第一钢铁厂在近几年内共同研制成功的一种高强度低合金钢筋。它是适合我国现有冶炼、轧制设备工艺的、符合我国资源情况的新品种钢筋。其性能良好、能满足设计使用要求,已进行了工业性试生产,并选择了若干试点工程应用,如杭州汽轮机厂的9米长、30吨和50吨后张自锚预应力混凝土拱形吊车梁、松江新五斜拉桥工
65Si2Ti steel bar is a kind of high-strength and low-alloy steel bar jointly developed by the Shanghai Institute of Building Research, Xinhu Iron and Steel Works and Shanghai No. 1 Steel Plant in recent years. It is a new type of steel bar that is suitable for China’s existing smelting and rolling equipment processes and meets China’s resources. Its performance is good, and it can meet the design and use requirements. Industrial trial production has been carried out, and several pilot project applications have been selected, such as 9 meters long, 30 tons and 50 tons post-tensioned self-anchored prestressed concrete arched cranes in Hangzhou Steam Turbine Works.
